Just like Disgaea 3 before it, Nippon Ichi is porting Disgaea 4 to the PlayStation Vita. There is very little known about Disgaea 4 Return at this point, but the trailer below does claim that this port will have the most content in series history. Disgaea 3: Absence of Detention (the Vita port) came with the PS3 version's DLC, so we wouldn't be surprised to see Disgaea 4 Return do the same.

Disgaea 4 Return releases in Japan on January 30th, 2014 for 6279 yen ($62.98 US), with a Vocal Song Best album as a first-print bonus. The port has not yet been announced for out west, but is likely inevitable.
